1 | VAPOR DIFFUSION, HANGING DROP | 7 | 289 | Peptide was included in protein buffer to a final molar ratio of 2:1 relative to protein. Reservoir solution contained 1.25 M sodium citrate, pH 7.0. Equal amounts (1.5 microliters) of protein (9 mg/mL) and reservoir solution were mixed and equillibrated against 500 microliters of crystallization buffer. |
